Heart rate, Apple Health and Health Connect

Stamina measures heart rate only with the watch. A run measured only with the phone has no heart rate.

With the watch

• If the watch measures the run, it measures everything, heart rate included.
• If you start it on the phone, Stamina opens the app on the watch: the phone measures GPS and the watch sends it your heart rate every few seconds.
• In the run's detail you see heart rate per kilometer, its chart and your heart rate zones, which are worked out from your age.

Apple Health, on iOS

• On the phone, Stamina only reads your daily steps to show them in your history. From the phone it doesn't save anything to Health.
• On the watch, it reads heart rate and distance during the run and saves the run to Health as a workout, with heart rate.
• It only does what you allowed. To record a run on the watch, it needs the location and Health permissions.

Health Connect, on Android

• On the phone, Stamina reads your daily steps to show them in your history and saves each run as a workout, with distance and heart rate.
• The watch doesn't save to Health Connect: it passes the run to the phone, and the phone saves it.
• It only does what you allowed. Without the permission, the run isn't saved to Health Connect.
